PROBLEM TO BE SOLVED: To provide a method for economically and advantageously producing a colored optical plastic lens by dyeing an optical plastic lens efficiently to an arbitrary color tone and density, and a colored optic obtained by the method. Provide plastic lenses for SOLUTION: A cured film of a water-soluble polymer is formed on the surface of an optical plastic lens, and then the lens is A method for producing a colored optical plastic lens to be dyed with an aqueous dyeing solution containing a disperse dye as a coloring component, and a colored optical plastic lens obtained by this method. |
